General rule of thumb: If your original remote does not have a dot ( .) or a dash ( - ) near the numeric buttons, the TV is does not have a digital tuner. These buttons are used to directly enter a digital channel number such as: 19.1 or 19-1. After looking at your TV specs, this TV needs a converter box if you plan on using a roof top antenna. I hope this was helpful, best wishes.

Hi, I am posting the instructions of how to set up the analog converter box :-Hope it will you.·Things you’llneed:Analog TV, antenna, two coaxial cable, and converter box ·Instructions:Step 1Unplug coaxial cable on the back of TV "antenna in" (RF) portStep 2Insert coaxial wire into the "antenna in" on the converter boxStep 3Use second coaxial wire and plug in the converter box, "out to TV" port. Plug the other end into “antenna in" on the TVStep 4Power on the converter box and TV. Change TV channel to 3 or 4. Follow on screen instruction to Complete setup.Step 5After setup you will begin to see more channels than before with better clarity. Some stations will broadcast two or three channels. Enjoy

Please let us know if that was helpful enough.
Good Luck & Thanks,
Shiv.

What's your source for signal? You need an antenna to be the capture source for your signal that has a wire going from the antenna to the INPUT of the box. That's usually coaxial input. The box is the middle component between your TV and antenna.

I just had a similar problem with this box - For the first month or two, I got the local NBC affiliate (KING-5 in Seattle) just fine on 5.1, then, after fiddling with my antenna setup, I lost it completely - NOTHING I could do would get it back. I tried a bunch of stuff - Multiple types of antenna, adding an antenna amp box, a handful of "homebrew" antennas - Nada. Yet all my other channels came in fine (although a couple were right on the edge - This box seems to need a "17" or higher on the signal strength - Some of my channels were reading in the 15-18 range, and suffering the "blockies" and sound dropout)

After hitting TVfool.com, found out that the KING digital signal is actually broadcasting on channel 48. Punched in 48.1, and there it was, clear as a bell, using nothing but a "wick" antenna (Basically, strip 4-1/4 inches of the outer braid off one end of a piece of co-ax cable, leaving the center wire alone, then plug the other end into the box) getting me a 23 signal strength. But a second or two later, the box is displaying "5.1" - Weirdness...

Reconnected a near top-of-the-line Winegard Yagi/Log-periodic antenna - VERY directional, and has some gain all by itself - and the signal jumped above 50.

Still couldn't "channel-up/channel-down" or punch in "5.1" to tune it, though - Channel 5.x was a "dead zone" as far as the box was concerned.

Re-did the "autoscan", and now, it's back to normal - I can channel-up/channel-down to it at 5.1, or I can punch it in as 5.1, or I can punch it in as 48.1, and it's all good.

Ah, the problem is likely your antenna. Make sure everything is properly hooked up, and that your TV is on and turned to either channel 3 or 4 (whichever the unit requires, or you can try both and see which works) then turn the converter on, and check the manual that came with it for a way to check for your antenna's signal strength.

If your signal is good, then use the menu button on the remote and look for an "autoscan" feature, or "autoprogramming", something along those lines, and let the unit look for channels for you (mine requires this before you can use it, not that it matters because my antenna signal is weak). From there you can access the channels manually.

Hey boykinpierce,The phrase "Smart Antenna" is often used to describe a multi-directional antenna or antenna array. These types of antennas are able to detect and automatically adjust to any changes in the TV signal strength you receive, and can generally be obtained through most major retailers. They primarily are used in areas where digital signals are weaker or somewhat inconsistent, and will attempt to optimize the signals they do receive before sending them to a TV or digital converter box.Please keep in mind that while some DTV digital-to-analog converter boxes may have built-in Smart Antennas, this particular model (RCA DTA800) does not appear to have this feature.If you're still not quite sure what to look for, please remember that you can always speak with a home theatre sales agent at your local Best Buy™ store for more information.Hope this helps you out.Sincerely,AaronGo Ahead.
